The spread of SARS-CoV-2 has led to an interest in using ivermectin (a potent antiparasitic agent) as an antiviral agent despite the lack of convincing in vivo clinical data for its use against COVID-19. The off-target prophylactic use of ivermectin adds a substantial risk of drug-drug interactions with pharmaceutical medications used to treat chronic conditions like diabetes and hypertension (metformin and hydrochlorothiazide, respectively). Therefore, this study aims to evaluate the potential drug-drug interactions between ivermectin with either metformin or hydrochlorothiazide.

Voriconazole is an antifungal agent and used as a prophylactic measure, especially in immunocompromised patients. However, there have been several reports of its adverse reactions, namely photosensitivity with intense inflammatory rashes and subsequent skin cancer development. To assess the effects of photosensitizing drugs voriconazole and hydrochlorothiazide (HCTZ) on the enhancement of UV-induced inflammatory responses and UV-induced tumorigenesis, we utilized Xpa-knockout mice, which is DNA repair-deficient and more susceptible to UV-induced inflammation and tumor development than wild-type mice.

Background: Periodic paralysis (PP) is an autosomal dominant muscle disorder characterized by periodic muscle weakness attacks associated with serum potassium level variations. It is classified into hypokalemic (hypoKPP), hyperkalemic (hyperKPP), and normokalemic (normoKPP) forms based on the ictal serum potassium level. HyperKPP and normoKPP are caused by mutations of the same gene SCN4A, the gene encoding the skeletal muscle voltage-gated sodium channel.

The renal outer medullary potassium (ROMK) channel mediates potassium recycling and facilitates sodium reabsorption through the Na/K/2Cl cotransporter in the loop of Henle and potassium secretion at the cortical collecting duct. Evidence from the phenotype of humans and rodents with functional ROMK deficiency supports the contention that selective ROMK inhibitors (ROMKi) will represent a novel diuretic with potential of therapeutic benefit for hypertension. ROMKi have recently been synthesized by Merck & Co, Inc.

Globally, the rate of development of myocardial diseases and hypertension is very common, which is responsible for incremental morbidity and mortality statistics. Treatment of ischemic hypertensive patients with diuretics such as hydrochlorothiazide (HCTZ) can precipitate myocardial infarction due to hypokalemia. This study was undertaken to evaluate the pharmacodynamic interaction of green tea extract (GTE) with HCTZ against ischemia-reperfusion induced myocardial toxicity.
